How to list all available RPC and extrinsics endpoints of a node?

Question

Is there a way to query a running (local) node and list all available RPC and/or extrinsic endpoints?

I want to create an overview for new team members and for our company, and maybe even pipe the output to a diagram tool!

Answer 1

curl http://127.0.0.1:9933 -X POST -H "Content-Type:application/json" -d '{"jsonrpc":"2.0","method":"rpc_methods","params":[],"id":1}'

The result example, extrinsic relates:

author_pendingExtrinsics
author_removeExtrinsic
author_submitAndWatchExtrinsic
author_submitExtrinsic
author_unwatchExtrinsic

You could also use substrate-api-sidecar to query a running local node. By default, it provides a series of endpoints to retrieve chain information (blocks, extrinsics and storage) from nodes. Highlighting here some extrinsics/transaction related endpoints :

/blocks/{blockId}/extrinsics/{extrinsicIndex}

/node/transaction-pool

/transaction

/transaction/dry-run

/transaction/fee-estimate

/transaction/material

but you can also check the full endpoints docs here
